Url: /api/profiles/:userId/lists refactored
Implemented getShoppingList

Also modified accountRepository to remove a shopping list id from the
set of a user
Refactored route for create shopping list
Update shopping list is now using new route and security

Update shopping list is now using the new route pattern.
Furthermore this method is now invoking the new securityPolicy object to
verify that a user has the right to update a list
GET shopping list now uses the new securityPolicy object
Refactor route DEL shopping list

Also modified the shopping list delete operation: we do not want to
remove the list, but just mark it as not active and remove its id from
the list of the shopping lists of the user. I still need to modify the
delete a little bit further: I need to search for the shopping list id
in all accounts and then remove it from all accounts
Started to implement new use cases to add items to shopping lists
Implemented route to add a new item to a shopping list
Trying to get an account no longer active, results in 404 response
